Publication number: 20230399609Abstract: A sperm sorting device adapted to collaborate with a temperature controlling component is provided. The sperm sorting device includes an upper portion, a lower portion and a porous layer. The upper portion is formed with an upper chamber. The lower portion is formed with a lower chamber. The upper chamber and the lower chamber are disposed vertically. The temperature controlling component is adapted to be disposed outside the upper portion or the lower portion to make the temperature of the upper chamber higher than the lower chamber. The porous layer is disposed between the upper chamber and the lower chamber. The porous layer is adapted to allow sperms to pass through from the lower chamber to the upper chamber and adapted to form a temperature difference between the upper chamber and the lower chamber. Besides, a temperature difference device adapted for the sperm sorting device is also provided.Type: ApplicationFiled: May 31, 2023Publication date: December 14, 2023Inventors: CHING-WEN CHANG, CHEN-YEN CHUNG, CHUNG-HSIEN HUANG, BOR-RAN LI
